System, device and method for determining error in robotic manipulator-to-camera calibration

Disclosed herein is a device, system and method for determining error in robotic manipulator-to-camera calibration. The method includes detecting a test object by a camera coupled to a robotic manipulator. One or more test points are identified on the test object based on a CAD model and pre-defined contact points corresponding to the test object. Arm poses are determined for the robotic manipulator to reach the test points on the 3D test object by using current robotic manipulator-to-camera calibration. While driving an end effector of the robotic manipulator based on the arm poses, any contact of the end effector on the 3D test object is recorded upon receiving a feedback from the 3D test object. An error is determined in the current robotic manipulator-to-camera calibration based on current position of the end effector relative to the one or more test points on the 3D test object.

A control device estimates a position and pose of an imaging device relative to a robot based on an image of the robot captured by the imaging device. A simulation device arranges a robot model at a teaching point, and generates a simulation image of the robot model captured by a virtual camera that is arranged so that a position and pose of the virtual camera relative to the robot model in the virtual space coincide with the estimated position and pose of the imaging device. The control device determines an amount of correction of a position and pose of the robot for the teaching point so that the position and pose of the robot on the actual image captured after the robot has been driven according to a movement command to the teaching point approximate to the position and pose of the robot model on the simulation image.

A direct pose feedback (DPF) control method applied to a DPF controlled machine is provided. The DPF control method includes a pose compensation control in addition to the position feedback control. The pose compensation control includes an initiation step, a reference system step, an actual pose calculation step and a position compensation step. The sum of the primary driving value and the compensation driving value is output to the driver of each of the motors. The advantage of the DPF control method is that the existing real-time position control loop in the controller can remain unchanged, while the pose compensation control is added to eliminate tool pose error resulted from geometric errors in the machine. The DPF controlled machine uses a pose measuring mechanism to measure the actual pose of the tool and to compensate the tool pose error. Hence, the DPF controlled machine is free of geometric errors.
